Thursday night and checking Facebook on my mobile before going to sleep. One of my friends is complaining about how hard it is to use Yahoo mail abroad. Problem logging in and now there’s some problem with the account. “Your E-mail account has exceeded its limit and needs to be verified, if not verified within 24 hours, we shall suspend your account. Click Here to verify your email account now.” And when you try to resolve it, it doesn’t even work. You just end up on the login page! Damn Yahoo!
Stop! This message is not about a problem with the mail system, it’s a very typical phishing mail. I responded with a warning, and yes, the link had indeed been clicked and the credentials entered on a page that looked like the Yahoo login page. That made my friend a phishing victim like so many other Internet users. It was the beginning of a long night trying to figure out how to change the mail password using a tiny mobile screen. But the case came to a happy end. The password was apparently changed before the attackers had a chance to take benefit from the account, thanks to the swift reaction.
How to spot a phishing attempt?
My friend is not a computer newbie, and did in theory know all this. But the attack succeeded anyway. How is this possible? Imagine that it is late in the night and you are tired. There are other people distracting you. You are traveling and really depending on your mail account. And on top of that, you have had problems and expect even more trouble with this operator. So this is a very typical situation where the fingers can be faster than the brains. This is really the optimal situation for an attacker to hit, and they happened to send this phishing mail at the
right wrong time. Honestly, are you sure this couldn’t happen to you?
Ok, so what should I do to avoid being phished?
As a practice, examine the link above and try to figure out where it points and what company it belongs to without clicking it.
Phishing @ Wikipedia.
Phishing is the act of attempting to acquire information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public.
This is the first in a series of posts about Cyber Defense that happened to real people in real life, costing very real money. A rainy, early spring day was slowly getting underway at a local council office in a small town in Western Poland. It was a morning like any other. Nobody there expected that this unremarkable day would see a series of events that would soon affect the entire community... Joanna Kaczmarek, a Senior Specialist in the council’s Accounting Department, rushed into her office a little late, but in a good mood nonetheless. Before getting down to work, she brewed herself a cup of coffee and played some music on her computer. Several days earlier, she had finally installed a music app on her PC so she could listen to her favourite tunes while she worked. This had taken some effort though, as she had needed administrator’s access to her computer. It took a lot of pleading and cajoling, but after a week the IT guy finally gave in. Joanna had no idea that she was opening a dangerous gap in the council’s IT system. That morning, Joanna launched, as she had countless times before, a government issued budget management application. With a few clicks, she made a transfer order for nearly twenty thousand zloty. The recipient of the money was a company that had won the contract for the renovation of a main road in the town. The whole operation took seconds. Two days later, the owner of the company phoned Joanna, asking about the advance he was supposed have received. “I can’t get the work started without that money”, he complained in an annoyed voice. Joanna was a little surprised and contacted the bank. The bank confirmed the operation, saying that there was nothing suspicious about it. Joanna, together with the Head of the IT Department, carefully ran back over the events of the day of the transfer. They found nothing out of the ordinary, so started checking what was happening on Joanna’s computer around the time before the transfer date. They soon found something: nearly a week prior to the date of the missing transfer, Joanna had received an email from the developer of the budget management software. For Joanna, the message hadn’t raised any red flags; the email contained a reminder about a software update and looked very legitimate. It contained the developer’s contact data, logo and telephone number. Everything was in order… Everything except for a change of one letter in the sender’s address. Joanna hadn’t noticed – a “t” and an “f” look so alike when you read quickly, don’t they? Unaware of the consequences, Joanna followed the link that was to take her to the update website. With just one click of her mouse she started a snowball of events that ultimately affected each and every resident of the town. Instead of the “update”, she downloaded dangerous spyware onto her computer. In this way, the cybercriminals who orchestrated the attack learnt that the woman was a Senior Specialist in the Accounting Department and was responsible for transferring money, including EU funds. The thieves lured Joanna into a digital trap, tricking her into installing software that replaced bank account numbers “on the fly”. As she was processing the transaction, the hackers replaced the recipient’s account details with their own, effectively stealing the money. Joanna would have been unable to install the fake update if she hadn’t obtained the administrator’s rights she’d needed for her music app. All she had wanted was to listen to some music while she worked. If only she had known what the consequences would be... After the attack was discovered, the Police launched an investigation. Joanna was just one of many victims. Investigators discovered that the malware infection was likely to have targeted computers used by local government workers in hundreds of municipalities across Poland. Law enforcement authorities haven’t officially disclosed how much money was stolen, but given the fact that losses may have been underreported, the estimated figures are in the millions of zlotys. On the top of that, Joanna’s town had to wait months for the completion of the roadwork. This was one of the largest mass cyber-attacks against local government in Poland. It certainly won’t be the last one... For small and medium sized enterprises, the average financial loss as the result of a cyber security incident is on average 380 000€. The risk and the lost is real. Don’t be an easy target. We help businesses avoid becoming an easy victim to cyber attacks by offering best in class end-point protection and security management solutions trusted by millions.
F-Secure Labs reported this week on a new WhatsApp scam that’s successfully spammed over 22,000 people. Spam seems to be as old as the Internet itself, and is both a proven nuisance AND a lucrative source of revenue for spammers. Most people don’t see what goes on behind the scenes, but spammers often employ very sophisticated schemes that can expose web surfers to more than just ads for Viagara or other “magic beans”. Spam typically tries to drive Internet traffic by tricking people into clicking certain websites, where scammers can bombard unsuspecting web surfers with various types of advertising. Profit motives are what keep spammers working hard to circumvent spam blocks, white lists, and other protective measures that people use to try and fight back – and it can pay off. Numerous spammers have been indicted and suspected of generating hundreds of thousands of dollars in revenue from their spam campaigns, with one study projecting that spammers could generate in excess of 3.5 million dollars annually. While most spam circulates via e-mail, the popularity of services like WhatsApp is giving spammers new resources to exploit people, and new ways to make money. Here’s a few ways spammers and cyber criminals are using WhatsApp to make money off users: Following Malicious Links: One way that cyber criminals use WhatsApp to scam people is to trick them into following malicious links. For example, a recent scam sent SMS messages to WhatsApp users telling them to follow a link to update the app. But the message was not from WhatsApp, and the link didn’t provide them with any kind of update. It signed them up for an additional service, and added a hefty surcharge to victims' phone bills. Sending Premium Rate Messages: Premium rate SMS sending malware was recently determined by F-Secure Labs to be the fastest growing mobile malware threat, and WhatsApp gives cyber criminals a new way to engage in this malicious behavior. Basically the users receive a message that asks them to send a response – “I’m writing to you from WhatsApp, let me know here if you are getting my messages”, “Get in touch with me about the second job interview”, and various sexual themed messages have all been documented. Responding to these messages automatically redirects your message through a premium rate service. Spanish police claim that one gang they arrested made over 5 million euros using this scheme – leaving everyday mobile phone users to foot the bill. Manipulating Web Traffic: A lot of spam tries to direct web traffic to make money off advertising. As you might imagine, this means they have to get massive numbers of people to look at the ads they’re using for their scams. Scammers use WhatsApp to do this by using the app to spread malware or social engineer large numbers of people to visit a website under false pretenses. F-Secure Labs found that people were being directed to a website for information on where they could get a free tablet. In March there was a global spam campaign claiming people could test the new WhatsApp calling feature. Both cases were textbook scams, and instead of getting new tablets or services, the victims simply wasted their time spreading misleading spam messages and/or exposing themselves to ads. WhatsApp and other services are great for people, but like any new software, requires a bit of understanding to know how to use. Hopefully these points give WhatsApp users a heads up on how they can avoid spam and other digital threats, so they can enjoy using WhatsApp to chat with their friends.

Espionage – it’s not just for James Bond type spies anymore. Cyber espionage is becoming an increasingly important part of global affairs, and a threat that companies and organizations handling large amounts of sensitive data are now faced with. Institutions like these are tempting targets because of the data they work with, and so attacks designed to steal data or manipulate them can give attackers significant advantages in various social, political and industrial theaters. F-Secure Labs’ latest malware analysis focuses on CozyDuke – an Advanced Persistent Threat (APT) toolkit that uses combinations of tactics and malware to compromise and steal information from its targets. The analysis links it to other APTs responsible for a number of high-profile acts of espionage, including attacks against NATO and a number of European government agencies. CozyDuke utilizes much of the same infrastructure as the platforms used in these attacks, effectively linking these different campaigns to the same technology. “All of these threats are related to one another and share resources, but they’re built a little bit differently to make them more effective against particular targets”, says F-Secure Security Advisor Sean Sullivan. “The interesting thing about CozyDuke is that it’s being used against a more diverse range of targets. Many of its targets are still Western governments and institutions, but we’re also seeing it being used against targets based in Asia, which is a notable observation to make”. CozyDuke and its associates are believed to originate from Russia. The attackers establish a beachhead in an organization by tricking employees into doing something such as clicking a link in an e-mail that distracts users with a decoy file (like a PDF or a video), allowing CozyDuke to infect systems without being noticed. Attackers can then perform a variety of tasks by using different payloads compatible with CozyDuke, and this can let them gather passwords and other sensitive information, remotely execute commands, or intercept confidential communications. Just because threats like CozyDuke target organizations rather than individual citizens doesn’t mean that they don’t put regular people at risk. Government organizations, for example, handle large amounts of data about regular people. Attackers can use CozyDuke and other types of malware to steal data from these organizations, and then use what they learn about people for future attacks, or even sell it to cyber criminals. The white paper, penned by F-Secure Threat Intelligence Analyst Artturi Lehtiö, is free and available for download from F-Secure’s website. [ Image by Andrew Becraft | Flickr ]
